annotate src/bytecode.c @ 4795:084056f46755
#'functionp gives nil for special forms, as in CL and GNU Emacs 23.
src/ChangeLog addition:
2009-12-31 Aidan Kehoe <kehoea@parhasard.net>
* eval.c (Ffunctionp):
Special forms no longer give t in this function, in accordance
with recent GNU Emacs and with Common Lisp.
tests/ChangeLog addition:
2010-01-01 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test #'functionp, making sure it gives nil for special forms.

| 30 FSF: long ago. | |
| 31 | |
| 32 hacked on by jwz@jwz.org 1991-06 | |
| 33 o added a compile-time switch to turn on simple sanity checking; | |
| 34 o put back the obsolete byte-codes for error-detection; | |
| 35 o added a new instruction, unbind_all, which I will use for | |
| 36 tail-recursion elimination; | |
| 37 o made temp_output_buffer_show be called with the right number | |
| 38 of args; | |
| 39 o made the new bytecodes be called with args in the right order; | |
| 40 o added metering support. | |
| 41 | |
| 42 by Hallvard: | |
| 43 o added relative jump instructions; | |
| 44 o all conditionals now only do QUIT if they jump. | |

| 1920 | 735 /* We used to GCPRO the whole interpreter stack before entering this while |
| 736 loop (21.5.14 and before), but that interferes with collection of weakly | |
| 737 referenced objects. Although strictly speaking there's no promise that | |
| 738 weak references will disappear by any given point in time, they should | |
| 739 be collected at the first opportunity. Waiting until exit from the | |
| 740 function caused test failures because "stale" objects "above" the top of | |
| 741 the stack were still GCPROed, and they were not getting collected until | |
| 742 after exit from the (byte-compiled) test! | |
| 743 | |
| 744 Now the idea is to dynamically adjust the array of GCPROed objects to | |
| 745 include only the "active" region of the stack. | |
| 746 | |
| 747 We use the "GCPRO1 the array base and set the nvars member" method. It | |
| 748 would be slightly inefficient but correct to use GCPRO1_ARRAY here. It | |
| 749 would just redundantly set nvars. | |
| 750 #### Maybe it would be clearer to use GCPRO1_ARRAY and do GCPRO_STACK | |
| 751 after the switch? | |
| 752 | |
| 753 GCPRO_STACK is something of a misnomer, because it suggests that a | |
| 754 struct gcpro is initialized each time. This is false; only the nvars | |
| 755 member of a single struct gcpro is being adjusted. This works because | |
| 756 each time a new object is assigned to a stack location, the old object | |
| 757 loses its reference and is effectively UNGCPROed, and the new object is | |
| 758 automatically GCPROed as long as nvars is correct. Only when we | |
| 759 return from the interpreter do we need to finalize the struct gcpro | |
| 760 itself, and that's done at case Breturn. | |
